in 'require': no such file to load -- spec_helper

Came across this error when trying out the ruby on rails tutorial section with rspec on a windows platform using jruby 1.6:
在使用 jruby 1.6 的 Windows 平台上使用 rspec 尝试 ruby on rails 教程部分时遇到此错误：

Found the answer which appears missing from the tutorial:
找到了教程中缺少的答案：
c:\rails_projects\sample_app>rails generate rspec:install
c:\rails_projects\sample_app>rails 生成 rspec:install

After running
运行后
rails generate rspec:install
Place your *_spec.rbfiles under (in your example) c:\rails_projects\sample_app\spec\model. Then specify relative path with require_relative
将您的*_spec.rb文件放在（在您的示例中）下c:\rails_projects\sample_app\spec\model。然后用 require_relative 指定相对路径
require_relative '../spec_helper'
回答by MBDJ
Run the following command
运行以下命令
c:\rails_projects\sample_app>rails generate rspec:install
This will put the spec_helper.rbfile in your /specdirectory
这会将spec_helper.rb文件放在您的/spec目录中

When you execute 'rails generate rspec:install', if you see 'Could not find generator rspec:install'error message, add gem 'rspec-rails'within :developnent, :testgroup in your project Gemfileas shown below.
执行时'rails generate rspec:install'，如果看到'Could not find generator rspec:install'错误消息，请'rspec-rails'在:developnent, :testgroup 中添加 gem ，Gemfile如下所示。
group :development, :test do
gem 'rspec-rails'
end
After this, execute 'bundle install'and continue with 'rails generate rspec:install'
在此之后，执行'bundle install'并继续'rails generate rspec:install'

This might be of some use - in the event rpsecwasn't installed properly on a Win7 environment.
这可能会有用 - 如果rpsec没有在 Win7 环境中正确安装。

I had the same problem but for a different reason:
我遇到了同样的问题，但出于不同的原因：
in my spork.preforkblock within my spec_helper.rbfile I had this line
在我的文件中的spork.prefork块中，我spec_helper.rb有这一行
Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}
but within one of the files that was being required above (spec/support/some_helper_file.rb) was a require 'spec_helper'call
但是在上面需要的文件之一 ( spec/support/some_helper_file.rb) 中有一个require 'spec_helper'调用
removing this unneeded require solved the issue
删除这个不需要的要求解决了这个问题
